How long can you store cold brew coffee?

How long can you store cold brew coffee?

Breville’s guide says homemade cold brew typically has peak freshness for around 5 to 7 days in the fridge, and is best within the first day or two. Unopened store-bought bottles can last up to 6 months from the listed brew date. Once opened, follow the label. Other sites quote longer times, such as up to two weeks, but we could not verify those, so treat 5 to 7 days as the safer figure for homemade.

How should you store it?

• Use an airtight container, preferably glass, to limit oxidation and stop it taking up odors.
• Keep it refrigerated as soon as brewing is done.
• After adding milk or a non-dairy alternative, drink it within 2 to 3 days.

Can you freeze cold brew?

Yes. Freezing can extend shelf life by about 3 months, but thawed cold brew often tastes muted. The guide suggests freezing in an ice cube tray rather than large batches, so you can drop cubes into iced lattes without watering them down.

How do you tell cold brew has gone bad?

• Smell and taste: sour, fermented or musty notes mean it is past its best.
• Appearance: white spots, fuzzy growth or murky, clumpy separation.
• Mold: discard the whole batch.

Does it matter that cold brew is not heated?

Cold brew is never boiled, so it has no heat step to kill microbes. That is a reason to use clean equipment, store it cold quickly, and not stretch the time. Never leave it out at room temperature for long.
